Because the demand for JHS PowerBar functionality is still high, other developers have built tools that replicate or improve upon its features. If you miss the JHS workflow, install these:

The Upright Extruder (by Eneroth) enables users to extrude profiles along a path while maintaining a vertical orientation, perfect for modeling roads on terrain or handrails for curved stairs.

Today, the PowerBar is gone, but its influence is everywhere. Every time you use a modern extension to quickly trim a line or select a similar face, you are experiencing the legacy of JHS. For veteran modelers, it remains the gold standard by which all SketchUp toolbars are judged.

Need to select every line with a specific tag (layer) or every face with a certain material? The PowerBar had a "Select Similar" tool that worked instantly. This was a massive time-saver for cleaning up imported CAD files or changing materials across a complex model.
